Massive Battery and Unmatched Endurance
The headline feature is the industry-leading 20,000mAh ExploVolt battery. Expect up to 5 days of heavy use and over 1,000 hours (≈45 days) of standby. 55W fast charging refuels in about 3.7 hours, and reverse charging turns the Tank 1 into a power bank for your other devices—ideal for week-long expeditions and power outages.
Rugged Design Truly Built to Last
True to its name, the Tank 1 is engineered like armor. It shrugs off 1.5m drops and can withstand single free falls up to 10m. Rated IP68/IP69K and MIL-STD-810H, it handles 2m submersion for 30 minutes and high-pressure water jets. Flame-retardant materials and marine-grade anti-corrosion ensure reliability across extreme heat, cold, moisture, and dust.
Dual Display Innovation
The main 6.78-inch FHD+ panel delivers 120Hz smoothness, 700 nits peak brightness, and Corning Gorilla Glass 5 protection with low blue-light comfort. A 2.01-inch rear display acts as a handy outdoor assistant—showing calls, notifications, music controls, weather, and quick tools—both readable in bright sunlight.
Ultimate Performance Engine
Powered by the 6nm MediaTek Dimensity 7050, the Tank 1 pairs up to 16GB LPDDR5 RAM with 512GB UFS 3.1 storage for fast app launches and ample headroom for large files. Advanced cooling sustains performance under load, while DokeOS 4.2 (Android 15) provides a clean, customizable experience with three years of updates.
Flagship-Level Imaging: Day and Night
The rear setup combines a 64MP main camera with a 20MP night-vision sensor for pitch-black captures—ideal for nighttime exploration, security, and creative work. The 50MP front camera produces sharp selfies and vlogs. Record 4K/30fps video, including underwater shooting thanks to full waterproofing.
Smart Features for Every Scenario
A 170-lumen dual-beam LED flashlight, a programmable shortcut key, an outdoor toolbag app, and glove mode elevate field usability. The IR remote controls appliances, while dual-frequency GPS supports BeiDou, Galileo, GLONASS, and QZSS for precise global navigation. Audio is loud and clear via a 100dB speaker. Connectivity includes dual-SIM 5G, Wi-Fi 6, Bluetooth 5.2, NFC, and microSD expansion up to 2TB.
